single speed Posted September 6, 2014 Share Posted September 6, 2014 This is the regulator box fitted to my milly If I push the bottom solenoid together the top left solenoid opens and the charge light goes out. The bottom solenoid will hold in, but not pull in by itself. Any suggestions please? Quote Link to comment Share on other sites More sharing options...
Zero-Five-Two Posted September 6, 2014 Share Posted September 6, 2014 Given my own Militants similar electrical issues, recently, I would advocate cleaning the contacts on each solenoid. I thought mine were reasonably clean, but Paul (the electrician who fixed mine) polished them with a piece of fine emery paper so you could try that.

Simon Daymond Posted September 7, 2014 Share Posted September 7, 2014 and then when you've done that, post some pictures of your militant (apologies if you've already done so) Quote Link to comment Share on other sites More sharing options...
attleej Posted September 7, 2014 Share Posted September 7, 2014 Dear All, I have an EMER covering this and a simple precis from SEME at Bordon. In my time in the TA with an AEC and Leyland Martian recovery these units gave nothing but trouble. My earnest recommendation is to fit a modern 24 Volt alternator. It might be possible to fit with the compressor leaving the generator to run the fan belts. I will look at our AEC at Bordon on Tuesday. I will scan and post on the forum the literature that I have got. It is very detailed and will enable anyone with the right skills to repair these items.

Zero-Five-Two Posted September 7, 2014 Share Posted September 7, 2014 fit a modern 24 Volt alternator While I agree this would solve all the charging problems at a stroke, mainly by doing away with the regulator box. I wanted to keep the dynamo set up on my Militant for the sake of originality. Not only that, now I know more about how the "box" works, I should be able to resolve any future problems myself. And anyway I've only had one issue in 3 years of Militant motoring, which I think isn't a bad average Quote Link to comment Share on other sites More sharing options...

John John, Any idea which spec of alternator would fit? Any literature would be of a great help! Stu Quote Link to comment Share on other sites More sharing options...
attleej Posted September 9, 2014 Share Posted September 9, 2014 Dear All, I have posted an extract from the relevant EMER on the forum. I will check our AEC at the museum to see if there is the space to fit an alternator on the compressor drive. There is always a debate about 100 % original or not. There is also one about safety and keeping the lights on and bright is very important if driving on today's modern roads. I quite like doing modifications that could have been done but for the bureacracy and pig headedness at within the MOD. It would have been possible to modify the AEC 10 ton fleet by fitting the alternator and regulator from the Bedford MK. It might have been possible to use EXACTLY the same parts as used on the Bedford. The relevant alternator and regulator should not be too difficult to find. Technical info about this alternator is easy find on the internet search "AC5R alternator". On the other hand, if you want the alternator that is most easy to sustain for the long term, go for the most common Bosch alternator fitted to the contemporary truck fleet. A commercial auto electrician could advise. For my money, I would go for the Bedford MK alternator as it was very reliable and is something that could have been done when the truck was in service.

Grasshopper Posted September 9, 2014 Share Posted September 9, 2014 If you want to keep it authentic looking, this chap produces electronic regulators for dynamos that fit inside the original regulator housing. http://www.dynamoregulatorconversions.com/about-me.php (also an entertaining write up on Lucas electrics at the bottom of the "about me" page!) Please note that I have no link to the company mentioned above, I found it while doing some research on dynamos. Vince Quote Link to comment Share on other sites More sharing options...
Gordon_M Posted September 9, 2014 Share Posted September 9, 2014 I've seen all those Lucas comments before, but they remain true ....:cool2: Worth a read. Quote Link to comment Share on other sites More sharing options...
Grasshopper Posted September 9, 2014 Share Posted September 9, 2014 I witness "smoke theory" on an occasional basis at work, made all the more impressive (in terms of quantity) when it is emanating from a 730V DC train or 110V battery set...
